In bowling, it’s not so much how a ball is delivered that counts as what the ball does once it is thrown down the alley. The Visek brothers need look no further than at each other to appreciate that point.

Riverhead High School senior D. J. Visek has an unusual two-handed throwing style that he adopted to get out of a slump. His younger brother, freshman Jon Visek, adheres to the more conventional one-handed approach.

The two dramatically different throwing styles have brought similar results. D. J. Visek said that once the ball leaves their hands, it has similar action. Quite often that action sends pins flying, producing spares and strikes.

That was the case Monday when both Riverhead bowlers excelled. Jon Visek capped a career-high 783 series with a career-high 290 game as the Blue Waves beat Southold, 30-3, in a Suffolk County League IV match at Wildwood Lanes in Riverhead. He delivered 11 straight strikes during the third game. In the first two games, he rolled a 248 and a 245.

D. J. Visek didn’t have a bad day, either, a 683 series from game scores of 203, 255 and 225. It was the fourth time this season that he hit 600 or higher.

The brothers combined for 50 of their team’s 79 strikes, 27 by Jon Visek.

Jon Visek started the day with a team-leading 206.04 average. D. J. Visek was third at 197.04, behind Forrest Vail’s 199.54.

The Viseks were the only Riverheaders to bowl in all three games. Nine Blue Waves bowled at least one game as Riverhead swept the three games, 922-747, 955-779, 1,028-717.

Among the other highlights for Riverhead were a 204 by Mark Stewart, who also employs a two-handed throwing style, and a 202 by Joe Gambino.

Riverhead, which entered the match in fifth place, has won 17 of 27 games and accrued 182 1/2 points.

Last-place Southold, which is 0-33 in games this season with only 22 1/2 points, was led Monday by Kaitlyn Kettenbeil’s 531 series, topped off by a 189 game. Jess Jerome added a 448 series, Emily Pressler had a 447, Mike Insogna a 427 and Jen Jaklevic a 290.
